The potential for "super grids" to stabilize energy supply during hurricanes is being explored by researchers at the Department of Energy's Oak Ridge National Laboratory. The Caribbean islands, traditionally reliant on expensive imported fossil fuels, are transitioning to harnessing local solar and wind resources. However, the prevalence of hurricanes poses significant challenges to solar

Princeton University researchers are developing new technology to integrate high-definition 3D holographic images into ordinary eyeglasses, promising a more immersive experience in virtual and augmented reality. Holographic images provide genuine depth as they are inherently three-dimensional, in contrast to monitors that only simulate depth on a flat surface. This intrinsic property allow

Estuaries, where freshwater rivers meet the sea, are not only ideal for birdwatching and kayaking but also serve as potential sources of renewable, "blue" osmotic energy. A recent study published in ACS Energy Letters highlights a breakthrough in this field, involving a semipermeable membrane designed to harvest osmotic energy from the salt gradients between these waters, effectively converting

Capacitors are crucial components in electronic devices such as smartphones and computers. They are made of dielectric materials that polarize on the application of the voltage. Currently, barium titanate (BaTiO3) is the most widely used material for capacitors. Barium titanate belongs to the perovskite group of materials, where a titanium ion resides within an oxygen octahedral cage. The materi

The typical process for creating synthetic diamonds involves high-pressure, high-temperature methods, using pressures around 5-6 GPa and temperatures between 1300-1600 C. Yet, researchers at the Institute for Basic Science (IBS), led by Director Rod RUOFF and his team, have developed a method to grow diamonds at 1 atmosphere pressure and 1025 C. This new approach utilizes a liquid metal alloy,

EU lawmakers on Wednesday approved a revision of the bloc's common agricultural policy (CAP) that scaled back some of the more eco-friendly requirements in a bid to appease farmers protesting what they say are overly strict rules. Farmers have been mounting rolling protests in countries across the European Union, from Belgium and France to Spain, Italy and Poland, over a long list of burdens

The United Nations said Wednesday it was launching a new Climate Resilience Fund aimed at boosting protections for "refugees and displaced communities" threatened by climate change. The UN refugee agency said it aimed to raise $100 million for the new fund by the end of next year to support refugees, their host communities and countries of origin hardest hit by climate emergencies. The a

A metal alloy composed of niobium, tantalum, titanium, and hafnium has shocked materials scientists with its impressive strength and toughness at both extremely hot and cold temperatures, a combination of properties that seemed so far to be nearly impossible to achieve. In this context, strength is defined as how much force a material can withstand before it is permanently deformed from its orig

Expanding material under tension usually results in a decrease in width, similar to inflating a balloon. However, a groundbreaking development by PhD student Noah Stocek and physicist Giovanni Fanchini at Western University exhibits a rare counter-example. At Interface Science Western's Tandetron Accelerator Facility, Stocek and Fanchini engineered two-dimensional tungsten semi-carbide nan

The existence of neutrinos, elusive particles suggested to account for missing energy and momentum in radioactive beta decay, was hypothesized in the 1930s and confirmed experimentally in 1956. These particles are known for only interacting through weak interaction, allowing trillions to pass through us harmlessly every second from cosmic sources like the sun. This interaction was pivotal in und

China's foreign minister on Friday urged visiting US Secretary of State Antony Blinken to address rising disagreements or risk a "downward spiral" between the two powers after months of efforts to ease tensions. Blinken, paying his second visit to the rival country in less than a year, voiced hope for progress but said he would directly raise areas of difference, which are expected to includ

As electricity demands soar with the onset of summer, East Coast cities in the U.S. look towards offshore wind projects in the Atlantic Ocean to bolster their power supplies. These projects, critical for meeting increasing electricity demands, face challenges in power prediction due to the wake effect, according to research from the University of Colorado Boulder and collaborators. A study

April 25, 2024 - Framatome inaugurated a $50 million expansion project at its Mill Ridge Road location in Lynchburg, Va, in the presence of local officials. This facility is one of three in Lynchburg, where the Operational Center of Excellence provides specialized training and tooling for servicing North America's nuclear power plants and developing new reactor technologies. "Today's groun

Kyoto University researchers, in collaboration with the University of Tokyo and Bridgestone Corporation, have developed a method to control pneumatic artificial muscles used in soft robotic actuators. The team leverages the rich dynamics of these components as a computational resource, enhancing robot flexibility and adaptability in disaster scenarios. "We've demonstrated the actuator's ca

Los Angeles CA (SPX) Apr 19, 2024 - Researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) are advancing fusion technology by integrating two established plasma control methods-electron cyclotron current drive (ECCD) and resonant magnetic perturbations (RMP). This combination has shown promising results in improving plasma management, crucial for generating electricity through fusion.
